Wikiperso is an eliom extension that can be used to provide
personal wikis. That is, when the user accesses a page
such as webserver.org/~bla/foo, a personal wiki is created
for the user bla, and registered to the url ~bla

Wikiperso currently takes two config options (in this order)

username is a regexp with one parameter, which must
extract from an url the name of the user for which the
wiki must be created, or fail if no wiki must be created.

wikiroot is a regexp containing the string $USER. Replacing $USER
by the user for which the wiki must be created must result
in the root url for this wiki (of course relative to the current
eliom root url). Correct values could be ~$USER or perso/$USER
